We are providing test results performed by us of the Taramp's TS-250x4 2ohm model.

We are using our professional Next-USB System with Level 3 AC/DC 1200A TH HE Sensor for power output measuring and our Level 2 AC/DC 400A Sensor for power input measuring.

We are using our own contracted import company - JFA Eletronicos for regulated 115/220v AC to DC Power Supply adjustable from 12.8-14.4vDC.

We are using Centech Infrared Temperature gun for monitoring ambient and Amplifier temperature.

We are using 8 1,000w Resistive banks mounted to Steel bars for output load and heat dissipation.

We are using SPL-Lab Software v2.6.10 in both Power and RTA mode.

Amplifier rated output-

72w x 2 8Ω 13.8v 5%THD

126w x 2 4Ω 13.8v 5%THD

Our Test Results-

(Because we provide more test data than anyone else, it will be impossible to accurately compare our data with another tester without knowing all of their values as well.)

QoSFRRTAT- ("cause-for-tat")

Quality of Signal Frequency Response Real Time Analyzing Test

This tests the FR amplitude curve by measuring the signal amplitude WITH a fixed load on it that is allowed to receive variables during test such as increase in temperature, etc that would likely happen in real world.

This amplifier hits the ratings right on the nose here. Amplifier rated for 5%THD, we are getting just a hair below it' rating at 1% and sometimes even below 1%THD by running it at 14.3v instead of 13.8v.

The signal FR video shows this amplifier is extremely flat response allowing it to be sufficiently used for all types of speakers and it's efficiency typically hovers in the 70% range which is great for such a small sized amplifier that literally fits in your hand.
